4 Claims. (Cl. 81-182) This invention relates to wrenchesof thetoggle-actuated plier-type and more particularly to pipe cuttingattachments therefor.

It is an object of the present invention to provide pipe cuttingattachments for toggle-actuated plier-type wrenches.

It is another object of the present invention to provide a novelcontainer adapted to be snapped on to one of the handles of the wrenchand into which the aforesaid pipe cutting attachments may be retainedwhen not in use.

Other objects of the present invention are to provide pipe cuttingattachments for toggle-actuated plier-type wrenches bearing the aboveobjects in mind which are of simple construction, inexpensive tomanufacture, have a minimum number of parts, are easy to use andefficient in operation.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Referring now to the figures, there is shown a toggleactuated plier-typewrench of well known construction adapted to be used with the pipecutting attachments 2,725,774 Patented Dec. 6, 1955 comprising thepresent invention. The wrench includes an elongated handle member 10 ofchannel formaation but having its outer end portion 11 closed and formedto provide a sleeve 12 through which threads a shank 13. The outer endportion of shank 13 is provided with a head 14 to facilitate rotation ofthe shank to effect the adjustment desired in a well known manner. Theopposite, or outer end, portion of the handle 10 is provided with astationary jaw 15 and inwardly of the jaw 15 and particularly theserrated working jaw face 16 thereof, the handle 10 is open.

A movable jaw 17 has its rear portion pivotally mounted'as at 18 withinthe forward portion of the handle 10. The pivotal mounting includes aninwardly directed wing or flange 19 at the inner portion of the jaw 17.The inner end portion of the jaw 17 has pivotally engaged therewith asat 20 a section 21 of an articulated lever 22. This lever 22 comprisestwo sections 21 and 23, the second section 23 of which extends withinthe handle 10 and has direct contact with the inner, or inserted, end ofthe shank 13. The section 21 extends beyond the pivotal connection 24between the sections 21 and 23 and said extended portion constitutes ahand grasp 25 whereby the jaw 17 may be readily moved toward the jaw 15to clamp an article between the jaws 15 and 17 in a well known manner.Engaged with the inner or rear end portion of the jaw 17 as at 26 is anend portion of a retractile member 27, the opposite end portion of whichis anchored or operatively engaged as at 28 to the handle member 10. Theretractile member 27 provides means whereby the jaw 17 is automaticallymoved to open position. The operation of the tool as a wrench isbelieved to be readily apparent from the foregoing description inconnection with the accompanying drawings, it being noted thatadjustment of the shank 13 permits the jaws 15 and 17 to be broughtcloser together when in the closed position.

In the practice of my invention, a pair of pull-over attachments 29 and30 are provided for permitting the wrench to be used for cutting pipes31.

The attachment 29 is of substantially U-shaped cross section and isadapted to slide downwardly on to the toothed upper portion of the jaw17, the edges of the sides of the attachment being integrally formedwith inwardly extending flanges 32 which fit under the shoulderedportion 33 of jaw 17 (Fig. 1), preventing upward displace ment of theattachment from the jaw. The attachment is locked longitudinally bymeans of a leaf spring 34 secured on its upper surface by means of arivet 35, the free outer end of leaf spring 34 mounting a detent 36which engages the toothed portion of the jaw. The forward upper portionof the attachment 29 is integrally formed with a right angle support 37in which the pipe 31 is placed. The detent 36 and spring 34 will lockthe attachment 29 longitudinally on jaw 17, while at the same timepermitting the attachment to be pulled off or adjusted longitudinallywhen suflicient force is applied thereto. 7

The attachment 31) is of substantially U-shaped cross section and isintegrally formed along its upper longitudinal edges with inwardlyextending flanges 33 which engage the shouldered portion 39 of jaw 15(Fig. l), preventing downward displacement of the attachment from thejaw. The attachment 3% is locked longitudinally on the jaw 15 by meansof a leaf spring 41) secured in position by a rivet 41,and provided atits free end with a detent 42 adapted to engage the teeth 16 in a mannersimilar to the detent 36. Theforward undersurface of attachment 30 isintegrally formed with brackets 43 be tween which is rotatably mounted acutting disc 44 by means of a shaft 45.

When the jaws 15 and 17 are broughttogether, as shown in Fig. 3, with apipe 31 supported on the angle support 37, the cutting edge of disc 44will cut the pipe 31 upon manual rotation of the latter.

A container 46 is provided of substantially U-shaped cross section andadapted to slide upwardly onto the handle 25. The outer end of thecontainer 46 is integrally formed with an extension 47 upon which issecured a leaf spring 4% by means of a rivet 49, spacers 50 beingprovided intermediate the leaf spring 43 and extension d7 whereby tofreely space the spring from the container. The central back portion ofhandle slides intermediate the spring 43 and the container (Fig. 6), theforward portion of the container being further resiliently secured tothe handle by means of leaf springs 51. Thus, the container 4-6 may bereadily snapped on and off the handle. \Vheu the tool is not being usedas a pipe cutter, the attachments 29 and 30 may be pulled off the jawsand retained in the container 46, the flanges 38 and 32 being retainedintermediate the spring 4% and the central wall of the container (Fig.6).

Referring now particularly to Figs. 7 through 10, there is shown amodified form of the present invention differing from the previous formin the manner of securing the attachments 52 and 53 to the jaws of thewrench.

In this form the attachment 52 comprises a top wall 54 integrally formedon its under surface with teeth 55 adapted to mesh with the teeth of jaw17, a side wall 56 and a curved bottom wall 57, all adapted to snuglyreceive therebetween the jaw 17, as shown in Fig. 10. Longitudinaldisplacement of the attachment 52 will thus be prevented by the meshingof the teeth 55 with the teeth of the jaw. Lateral displacement will beprevented by a spring clip 58 pivotally mounted in the outer face ofbottom wall 57 by means of a rivet 59, the free end of the spring clip58 being provided with a lug 60 adapted to engage the side of jaw 17remote from side wall 56. The spring clip 58 on the face remote from thelug 60 is formed with a knurled portion 61 to facilitate rotation of thespring clip and lug into-the closed or looking position of Fig. 8.

The forward portion of the bottom wall 57 is integrally formed with anose 62 provided on its upper surface with a right angle support 63similar to the support 37 of the first form.

The attachment 53 comprises a bottom wall 64 integrally formed on itsupper surface with teeth 65 adapted to mesh with the teeth 16 of jaw 15,a side wall 66 and a curved top wall 67, all adapted to receive snuglytherebetwcen the jaw 15, as shown in Fig. 10. Thus, the teeth 65 preventlongitudinal displacement of the attachment. Lateral displacement isprevented by means of a spring clip 68 pivotally mounted on the outerface of top wall 67 by means of a rivet 69 and provided on its free endwith a stop or lug 70 adapted to engage the face of jaw 15 remote fromside wall 66. The spring clip 68 on the face remote from stopper 70 isprovided with a knurled extension 71 to facilitate the rotation of thespring clip into the locking position.

The attachment 53 is integrally formed at its forward portion with apair of brackets 72 laterally spaced apart (Fig. 8) and provided withtransversely aligned openings in which is positioned a set screw 73, theopening in one of the brackets 67 being threaded, as at 74. A cuttingdisc 75 is rotatably mounted on the set screw 73. In this form theattachments 52 and 53 may be snapped on from the sides of the jaws andretained thereon by means of the spring clip locking arrangement. Theseattachments are particularly adapted for thin jaws.

Referring now particularly to Fig. 11, there is shown a still furthermodified form of the invention, and differing from the attachment shownin Fig. 9 in the provision of auxiliary rollers 76 and 77 rotatablymounted in brackets 78 and 79 provided on the upper surface of the anglesupport 63. This modified attachment 52 is particularly adapted forcutting heavy pipe.

In other respects the form of the invention shown in Fig. 11 is the sameas that shown in Figs. 9 and 10 and like reference numerals identifylike parts throughout the several views.

Referring now particularly to Figs. 12 and 13, there is shown a stillfurther modified form of attachment comprising a bottom wall 80 and sidewalls 81 and 82 having arcuately shaped upper edges. The jaw 15 isadapted to be received downwardly between the side walls 81 and 82, theupper surface of bottom wall 80 being provided with teeth 83 adapted tomesh with the teeth 16 of the jaw 15 whereby to prevent longitudinaldisplacement. The attachment is retained against downward displacementfrom the jaw by means of a set screw 84 and a wing headed screw 85, eachadapted to engage a side of the jaw 15 above the shoulders 39.

It will be noted that the side wall 82 is provided with an elongatedopening 86 within which the wing screw moves. Thus, the attachment isadjustable along the jaw. The front of the attachment is provided with anose 87 which rotatably mounts the cutting disc 88 by means of the shaft89.
